Title: Test for virulent revertants in attenuated live vaccines
IPC: C12Q1/70
Filed: 1991-11-06
Abstract: The present invention concerns a method of evaluating the safety of live attenuated vaccines which is based on detection and measurement of the incidence of genetic changes associated with reversion to virulence in vaccine microorganisms. The method based on PCR and restriction enzyme analysis was developed and used for determination of the proportion of mutants contributing to neurovirulence of type 3 live oral poliovirus vaccine. The correlation between the neurovirulence of OPV lots revealed by the monkey test and the abundance of mutant virus containing cytidine in the positon 472 was discovered. The amount of these mutants increases upon passages of the virus in cell cultures at a rate dependent on the cell type, cultivation conditions and the seed virus stock. The present invention can be applied for the safety test of lots of live vaccines and in-process control of vaccine manufacturing as well as the approach for the optimization of conditions for manufacturing of safe vaccine and selection of the seed virus and cell substrate.

Title: Erosion resistant mixing impeller
Inventor: WEETMAN RONALD J
IPC: B01F15/00
Filed: 1994-01-06
Abstract: In order to extend the life of mixing impellers which circulate materials, and particularly which suspend solids, in the form of particles which erode the blades of the impellers and place a practical limit on impeller speed and/or angle of attack due to increased erosion at high flow velocity (erosion being a function of the cube of the velocity), the blades are constructed from blades into an airfoil configuration which does not limit the thickness of the plates and thereby allows the use of thick plates having extended life. An erosion resistant layer is located at least over the leading edge region of the blade and the shape of the blade reduces velocity of flow over the leading edge; the camber of the blade being maximized midway between the leading and trailing edge. The suction surface of the blade in the region subject to erosion is continuous thereby avoiding discontinuities which form vortices which enhance erosion. Fins, which may be at the tip on the suction side of the blade from midway between the leading and trailing edges to the trailing edge reduces tip vortices thereby further extending blade life in erosion-producing environments.
